What is renal purpura_Which department does purpura belong to

Renal purpura is a relatively common disease, which is a kidney disease caused by purpura. The incidence of purpura is still relatively high, and there are many causes of the disease, such as blood problems or immune problems, which are major factors leading to the onset of purpura. Therefore, when purpura occurs, you can go to the hematology department or the immunology department. Next, I will introduce you to some relevant knowledge about purpura!

1. Which department does purpura belong to?

You can choose hematology or immunology.

Purpura is a general term for color changes of the skin and mucous membranes due to bleeding. The clinical manifestations are petechiae, purpura and ecchymosis, which are generally not higher than the skin surface. Only in allergic purpura can they be slightly raised. They are purple-red at first and do not fade under pressure. Then they gradually become lighter and turn yellow and disappear in about two weeks.

Diseases that cause subcutaneous bleeding are collectively called purpura, most of which are allergic purpura (She-Henrson-Heinz disease) caused by vascular system disorders, and idiopathic thrombocytopenic purpura caused by thrombocytopenia.

Definition of Purpura

A general term for color changes in the skin and mucous membranes following bleeding. Purpura is not the name of a disease, but a symptom of multiple diseases. Bleeding spots in the range of 2-3mm are called purpura, and those larger than 0.5cm are called ecchymosis. There are many different types of purpura based on different causes and clinical manifestations. Purpura is the most common clinical manifestation of hemorrhagic diseases. Its clinical manifestations include bleeding spots, purpura and ecchymosis. Generally, they do not protrude above the skin surface. Only in allergic purpura can they be slightly raised. They are purple-red at first and do not fade when pressed. Then they gradually become lighter and turn yellow and disappear in about two weeks.

Pathogenesis of purpura

1. Vascular purpura: It is very common. It is a hemorrhagic disease caused by abnormalities in the structure or function of the vascular wall, that is, damage to the vascular wall or its increased fragility and permeability. It is not accompanied by abnormalities in the quality and quantity of platelets or blood coagulation disorders. Except for a possible positive result in the arm beam test, there are no other abnormalities in the examination. These purpuras are caused by increased permeability and fragility of the blood vessel walls or by the deposition of immunoglobulins (IgG, IgM) and immune complexes in the blood vessel walls.

2. Thrombocytotic purpura: The most common, mostly caused by thrombocytopenia, thrombocytosis and abnormal function. If there are purpura or blood blisters on the buccal mucosa, it often indicates severe bleeding and should be treated actively.

3. Coagulation disorder: including coagulation factor deficiency, anticoagulants in the circulation or hyperfibrinolysis. Generally speaking, bleeding caused by coagulation disorder is mainly manifested as joint effusion, muscle hematoma and visceral bleeding, less often as skin purpura, and only sometimes as large ecchymosis, and there are obvious abnormalities in coagulation examination.
